Making the Power Connec on
The power wires should be 14 AWG. Smaller wires may be used, down to 18 AWG, but verify that they meet
your local electrical requirements.
Connect the power to the unit as follows.
ELECTRICAL WARNING: Ensure that power is disconnected from wiring
prior to handling! Check the voltage ra ng next to the power connector
- verify that it matches the power source.
1)
Remove the plug por on of the power connector by loosening the two cap ve moun ng screws.
2)
Strip back 1/4" off the insula on of the wires that will connect the unit to the power source.
3)
Loosen saddle screws and insert each conductor firmly into a terminal hole of the plug
(note: this connec on is polarity sensi ve for Low Voltage power input)
4)
Visually inspect that no strands of wire are straying out of the hole, poten ally shor ng to ground or
the other conductor. Tighten the saddle screws un l the wires are secure.
5)
Re-insert the plug into the power connector and secure the two cap ve moun ng screws.

2.3.3 Connec ng to the Console Port and the Alarm Port
2.3.3.1
Console Port
The Console Port enables configura on of the device and is connected by a serial cable to a PC.
For hardware installa on see "Connec ng Network Cables", below. For startup and configura on
informa on see
MNS-DX Administrator’s Guide
.
2.3.3.2
Alarm Port
The alarm port carries alarm signals to provide no fica on of events specified by so ware configura on. The events
that can be set to trigger alarms are described in the
MNS-DX Administrator’s Guide
. Wire the pins of the alarm port
appropriately depending on whether your downstream alarm system expects normally open or normally closed
opera on. See
Table 1-11
for alarm port pin-out. Table 2-1 below defines the ra ngs of the alarm port contacts.
